Active carbon water filter

Active carbon water filter 1)operation stability 2)low energy consumption 3)low efficiency

1:Outline

Along with the development of China's industrial and agricultural production, the quality of the water pollution also will increase, and the requirements for water treatment more and more is also high

Activated carbon is a kind of very good adsorbent. It can absorb the water of many organic or promise of ionic or non-ionic pollutants. The removal of organic carbon, in addition to the adsorption effect, still exist in the degradation of biological chemistry function and the surface of the catalytic activity. Activated carbon the biggest characteristic is to remove the water microbial degradation or difficult to general oxidation method can't decomposition of organic pollutants solubility

But through the use of activated carbon filter, not only high investment, and use the cycle is short, renewable complex, loss is big, high cost, operation of trouble. Therefore, in our country that activated carbon water treatment field application by a restriction.

Our factory production of biological active carbon adsorption tower series products, and usually the activated carbon filter, it is characterized by the use of cycle is long, low energy consumption, low efficiency, effect is good incomparable a bit, and has the following characteristics of the process.

1:For the drop flow fixed bed process

2:With gas and water to wash the two sets of system

3:To prevent carbon loss in the device

4:Have put an end to the flow of short function

5:Has the hydraulic pack carbon and discharge carbon facilities

6:Have in oxygen filling environment of operation conditions

2:Active carbon adsorption principle

For the other particles activated carbon water organic pollutants especially with physical adsorption effect, its adsorption and enrichment of the size of the performance, and the surface area of the carbon relevant, the larger the surface area, its adsorption and enrichment of the greater the performance.Particles of activated carbon surface has a lot of micro hole, therefore it has a very large area, generally 650 ~1200m2/g therefore, the adsorption and enrichment performance is very strong. Because the surface of the activated carbon has a large amount of micro hole, have good adsorption and enrichment performance, and therefore the most easily of microorganism attached on the surface of the carbon, oxygen enough in the condition, the microbes living to reproduce, and gradually formed a biological membrane. Activated carbon will organic pollutants in adsorption occurred in their surface, just for microbial providing rich nutrition. Therefore, be active carbon adsorption of organic pollutants degradation continues. Active carbon adsorption organic pollutants and the edges are microbial degradation of the adsorption---suck solution process, make active carbon adsorption capacity to get part of the response, so that can keep a certain active carbon, so extended the use of activated carbon cycle.

Our factory production of biological active carbon adsorption tower series, is to speak of activated carbon physical adsorption effect and microbial degradation of the biochemical role of combining the water treatment technology. Therefore, not only can improve the water treatment effect and processing system operation stability, and can prolong the life cycle of activated carbon, reduce the operation cost and energy consumption.
